Associated with the cam track" 20" at a point intermediate the receivingend ofthecarrieruand the ad'iacenttfleX; Itwill be V readily from the oftile in laterally spaced, disposed rovvs,a horizontally movable carrierrcsure imposed by the spring fingers 2| is exerted for a Very shortinterval of time, whereupon the respective arms I8 are released and thespring 20a abruptly rocks the spring finger away from the adjacenttubing. The arrangement is such that each of the lengths of tubingissimultaneously engaged by thespring'finge -andalso;;i s released atthesame time.

Near the discharge end of the carrier C; the cam tracks 28 are similarlyprovided with cam surfaces 23 to effect w I Y r 7 to exert pressureagainst the rear end of each severed tile section from the carrier. eachtile section, the front end of such section .10 similarroc i l movementjust prior to its discharge ,4 By :clampingthe rear end of is held inits horizontal position; so that it will engage a conveyor D. It will bemanifest that without exerting such clamping pressure uponeach tilesection, the front end of the til would tend to incline downwardly asthe forward tray moves downwardly from its horizontal position.Heretofore, it ha been necessary manually to remove the tile sectionsfrom the carrier and place them on the conveyor D. Such manual labor iseliminated since the tile sections move carrier to the conveyor D. Assoon as the tile section, is delivered to the conveyor D, the clampingpressure is released from the rear end portionof'the tilesection.

It is to be understood that numerous changes in details of construction,arrangement and operation may be eifected without departing from thespirit of the invention especially as defined in the appended claims. a

What I claim is: V l

1. The method'of forming clay tiles consisting in horizontally advancingtwo endless tubes in parallel side by side relation upon an endlesscarrier, applying pressure advance to equalize the currently severingthe tubes into predetermined sections, and applying pressure to therear'end portion of each section at the time of dischargefrom-thecarrier to cause same to maintain its horizontalposition'thereof. a a
